Problema Solution
Henry is standing on a catamaran at an elevation of 10 feet relative to sea level.
His friend Thomas is scuba diving at an elevation of -12 1/2 feet relative to sea level.
Which friend has greater elevation?
Which friend is farther from sea level?
Answer provided by our tutors
A level greater than zero is a greater elevation, hence 10 feet.
The absolute difference from the sea level is the absolute value of 10 compared to -12 1/2, therefore the scuba diving is from from sea level.
